Plates of a heat exchanger plate pack are formed by a stack of plates defining at least two independent fluid flow circuits, each circuit comprising a central heater part and a border with a smooth surface. A cutout is produced on corners of each plate and on the border to be connected, of each plate to the adjacent plate, a fold is made in order to form a first flange. On this first flange a fold is made in order to form a second flange laying parallel to the central part of the corresponding plate and directed outward from the plate. The plates are superposed and held by applying the second flange of each plate to the second flange of the adjacent plate. A continuous sealed weld bead is made by completely melting the second superposed flanges of adjacent plates.
A method for assembling the plates of a plate pack for a heat exchanger formed by a stack of plates together defining at least two flow circuits for two independent fluids and each comprising a central heat-exchange part and borders with a smooth surface, comprising:
A plate pack for a heat exchanger, wherein plates superposed and assembled by the method according to any one of the preceding claims.
